DS18S20/T&R - 1-Wire Digital Thermometer on Cut Tape

Each DS18S20 has a unique 64-bit serial code, which allows multiple DS18S20s to function on the same 1-Wire bus; thus, it is simple to use one microprocessor to control many DS18S20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment or machinery, and process monitoring and control systems.

Key Features

• Unique 1-Wire interface requires only one port pin for communication.
• Each device has a unique 64-bit serial code stored in an onboard ROM.
